Product Overview

The 330104-00-05-90-02-05 is a high-performance metric-threaded proximity probe from the Bently Nevada 3300 XL series, specifically designed for non-contact displacement monitoring. This 8 mm transducer converts the physical gap between the sensor tip and a conductive target into a precise voltage signal, enabling continuous observation of shaft vibration and axial position.

This specific configuration is built for large-scale industrial machinery where long-distance cable routing is necessary. Featuring a 9.0-meter integrated lead and a stainless steel armored jacket, it provides the mechanical resilience required for deep-reach installations within steam turbines, centrifugal compressors, and high-speed pumps. As a critical component of Turbine Supervisory Instrumentation (TSI), it ensures high-fidelity data acquisition for asset protection and predictive maintenance.

Engineering and Durability

The 330104-00-05-90-02-05 utilizes patented Bently Nevada manufacturing processes to maximize service life in harsh process environments:

• TipLoc Molding: A proprietary bonding technique that creates a molecular-level seal between the Polyphenylene Sulfide (PPS) tip and the probe body, preventing moisture or oil from wicking into the sensing coil.

• CableLoc Design: An internal anchoring system providing up to 330 N (75 lbf) of pull-out strength, shielding the electrical junction from mechanical strain during installation.

• Flexible Armor Protection: The FEP-insulated coaxial cable is encased in flexible 304 stainless steel armor to prevent abrasion and accidental cutting in complex machine housings.

• EMI/RFI Immunity: Advanced circuitry ensures high signal-to-noise ratios, meeting European CE requirements without the need for specialized shielded conduit.

Primary Applications

This 9-meter proximity transducer is optimized for a variety of machinery health monitoring tasks, including:

• Radial Vibration Analysis: Measuring shaft dynamic movement within fluid-film bearings.

• Axial Thrust Monitoring: Tracking shaft position to prevent internal rotor contact.

• Phase Reference: Serving as a Keyphasor sensor for timing and RPM measurements.

• System Integration: Fully interchangeable with 3300 XL Proximitor sensors and 3500 Series machinery protection racks.

• Hazardous Zone Deployment: Certified for use in Zone 0, 1, and 2 environments.
